GUN-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 399,452, dated March 12, 1889.

Application filed December 20, 1888. Serial No. 294,162. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES 'lonmrvson, of Syracuse, county of Onondaga, in the State of New York, a citizen. of the United States, have invented certain new and useful Improvements in GunCleaners, of which the following is a specificatioi'i, reference being had to the acct'nnpanying drawings, in. which- Eigure 1 is a side elevation thereof. Fig. 2 is a sectional elevation on 90. Fig. is a like view on a line at a right angle to .r Fig. ".i: comprises sections and elevations of parts detached. Fig. 5 is a side elevation of a varied construction. Fig. 6 is a sectional. elevation of the same, showing another side. Fig. 7 is a sectional elevation on line 1 1 Fig. 8 is a like view on line u- 11. Fig. 5) is a plan view of the body. Fig. 10 is a sectional elevation of the outer end. 11 is a plan View of the inner face of the tension -nut marked 19.

Myinventi on relates to devices for cleaning guns and firearms when connected to a rod.

My object is to produce a cleaner which will clean and polish the barrel, and is also adapted to remove any accumulation of lead, which frequently and quite generally colleetsin the choked portion of a shotgun-barrel, and to remove it without scratching, marri ng, or dainaging the interior of the barrel.

It consists in the several novel features of construction hereinafter described, and wh ieh are set forth in the claims hereto annexed.

Itis constructed follows: A is the cleaner, in which 1 is the body, consisting of a rod having threaded studs 2 3 upon its ends and provided with a longitudinal slot, at.

5 is a metallic disk provided with slots (5 opposite each other, and with central openings adapting it to slide freely upon the stud 2.

7 is a nut screwed onto the stud 2, and provided with a flange, 8, upon its inner end.

9 is a coiled. spring slipped onto the stud 2 between the nutand disk 5.

10 is a cap fitting over the flange of the nut 7 by means of an inward rim on its outer end, and inclosing the spring 9 and disk 5, said rim fitting loosely over the stud 2, so that the not can be screwed up without any difficulty.

11 is a like cap provided with an inward rim, which rim fits over the body 1 and abuts against the inner face of the collar 12 upon or between the stud and body 1.

l3 13 are flat pieces of spring metal pro vided with teats 1t 15, fitting as to studs and teats it into the slots (5 in the disk 5, and as to the teats 15 these fit under the edge of or are screwed to the cap 11. The caps 10 11 are connected by and secured to the longitudinal side bars, 1o.

17 is a pieceot' wire woven cloth of any material harder than lead, but softer than the iron of a gun-barrel, and is of tubular or cylindriez'il form.

18 is a piece of leather, felt, or other lllI- terial, secured upon the outer surface of the spring 1 2-3, and adapted to be used as a polisher or scrubber. The springs 13 stand out in a bowed or bent form upon. two sides of the cleaner, so as to project all of the time to a certain extent-usually in a shotgun-cleaneu about far enough to make it fit closely in the gun-barrel. If it does not fit tightly enough, I screw up the nut 7, thereby compressing the spring H, which crowds the disk inward,and this causes the springs l? to bow outwardly more than before. and so [it tighter in the barrel.

\Vhcu wish to remove the lead which usually accumulates in the choked portion of a clmke'borcd shotgun, I pull the sleeve or tube of wire-cloth on over the springs 13, and their outward spring will tcusionally hold the wire-cloth and centrally expand it: into somewhat of an ovoid form. Then when the cleaner is drawn back and forth in the gun-barrel with a straight draw or twisting motion, the rough surface of the wire-cloth will quickly cut away and remove the lead, acting somewhat like a file.

hen the cleaner, either with or without the wire-cloth sleeve, reaches the contracted or choked portion of the barrel, such decrease in the diameter operates to compress the springs 13, which operate to push the disk 5 outward and compress the spring 9, which spring 9 reacts as soon as the cleaner leaves the contracted part of the barrel and throws the springs 13 outward again. This elasticity in the gun-clean er permits and forces it at all times to fit the barrel without binding. The projecting end of the stud 3 screws into the end of the cleaning-rod; also, when I unscrew the nut 7 entirely, all of the parts will slide off from the body 1, and I can inserta cloth into the slot '21: and use it then as a swab or rag cleaner. These parts, when so removed, are all held together between and within the end caps, ready to be puton again and screwed up.

Upon the second sheet of the drawings I show another mechanism for expanding the 7 springs 13, consisting of the following features of variance in construction: I leave out the disk and spring 9. I extend the ends of the springs 13 through the cap 11, as atir, Fig. 7, forming a lip, 20, upon the ends,it' desired. I place a nut, 19, upon the body 1 between the collar 12 and the plain portion of the body, either providing it with a concavity, 22, in its inner face, when I form lips on the springs to receive such lip ends, or leavingthis inner face plain where the spring ends are plain; also, upon the outer end of the body I form a heath- 23, which, when inserted through the elongated hole 24: in the cap 10 and twisted, as shown by the dotted lines in Fig. 10,1.ocks the frame upon the body.

I expand the springs 13 by screwing n p the nut 19. I can also bend the springs 13 before they are inserted, secure one or both ends to the cap or caps, or leave both ends free, adapting the ends of the springs to slide under one or both caps when they are compressed.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a gun-cleaner, a wire-cloth tube, in combination with expansible springs mounted in a frame-work, and means for expanding or contracting the springs, substantially as described.

2. A gun-cleaner consisting of spring side pieces mounted in a frame, the frame mounted upon the body of the cleaner, a take-up spring within the frame, and a tension-nut, in combination, substantially as described.

7 A gun-cleaner consisting of spring side pieces mounted in a frame, the frame mounted upon the body of the cleaner, and a tensionnut, in combination with a wire-cloth tube drawn longitudinally over the spring side pieces.

1-. In a gun-cleaner, a wire-cloth tube ti ttin g over and in combination with an elastically eon'ipressible and expansible body, substantially as described.

5. In a gun-cleaner,awire-cloth tube fitting over and in combination with an elasticallycompressible and expansible body, and means for regulating the expansion and compression, substantially as described.

In witness whereof I have hereunto set my hand this lst day of December, lSSS.
